Except at very low levels, uncorrected photometric determination of bacterial cell densities showed a decreasing proportionally to actual cell density or dry weight. A standard curve was prepared to convert photometric readings to truly proportional optical density values. With one dry weight determination, optical density values may be converted to absolute dry weight values.
除了在极低水平外,未经校正的细菌细胞密度光度测定显示其与实际细胞密度或干重成比例下降。制备标准曲线以将光度读数转换为真正成比例的光密度值。通过一次干重测定,光密度值可转换为绝对干重值。
